To all whom it may concern;

Be it known that I, HENRY J. Lure, a citizen of the United States of America, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Waste-Pipe Connections. for Closet- Bowls and I hereby de-l clare the following to be a full,- clear, and

exact description .of' the invention, such aswill enable others skilled in the art to which it pertains to make anduse the same.

' This invention relates to improvements in a waste-pipe connection .for water-closets and the like.

The object of this invention isto provide a i as tight connection between the closet-"- owl and the waste -pipe which can be easily assembled and adjustedand which will also I flanges 9 and 10, which project inwardly, and

serve as a rigid support for the closet-bowl independently of the floor.

With this object in view my invention consists of the features of construction and com bination of parts as. described in the specification, pointed outin'the claims, and illustrated in the accompanying drawings.- In the accompanying drawings, Figure 1 shows aip'ortion of a c oset-bowl connected with a waste-pipe by my improved oonnec-. tion, the wasteipeand connection being shown iin'centra section. Fig. 2 is a top. plan of the connection with the bowl removed. -Fig. 3 is a section on line 3 3, Fig. 1. Fig. 4 is a section on line 4 4, 1. Fi 5 is a section on line .55, Fig. 4.- Fig. 6 1s a section on line 6 6, Fig.4., Again referring tot-he drawings, 1 represents asection of a floor on which'is mounted a closet-bowl 2 of theusual construction havplate 3 is ormed a recess'4. v v 5 re resents a metallic or. earthenware pipe, w ich is arranged beneath the floor 1 a eater or less distance, according to the ing a base-Pl ate 3. In the bottom of the base-' ling orl'connectiom'the female member of whichcom rises twoya'nnular flanges ti and 7 which are ormed integral with the rim of the waste-pipe and constitute the sides of the seal chamber orcupa8." 'At the top of each of the 'sides' of the 'vseal cup are arranged below these flanges on the sides of the cup are. formed lugs ll and 1 2 on the respective sides 6 and 7. The male member of the connection comprises a short section of pipe 13, Whichis-arranged to fit into the; cup 8. Oil the lowerrim of the pipe 13 are formed lugs 14, which preferablyproject beyond both the interior and exterior surface. thereof. The upper end of the. pipe-section 13 is. screwthreadedfandthereon is arranged a similarly-screw-threaded circular plate 15, which fits into the recess in the bottom-of the -b'as'e-.

plate 3.of '-the closet;bowl and is secured thereto bybolts 16. Within -the cup 6 is rrran 'ed a seal 18, of lead or other suitable .naterial, and, as shown in the drawing, this seal is arranged between the interior surface cup, so as. to completelyfill the s ace between 7 OH ofthe pipe 13 and the inner-side 7of the seal-'- the ipe and said inner side. e lugs 14 on I the interior of the pipe 13 and the In s 12 on the side of the cup will be emlz'edde in the seal,-and the seal will abut against the flange 10. Therefore after the sealjhas been lacedin. the cup the pipe-13 will be securely ocked I in the cu so that it cannot be withdrawn therefrom and also so that it. cannot turn therein. A ring 21, having an exterior diameter equal to the interior diameter of the .pipe 13, is arranged within the1pipe 13, so'as toreston 'said cu 8;- The inner tace of this ring 21 is bevele as at'22,. s o;that thering' forms a deflector which preventsanywaste materiallodgingon'thecup 8; *Areducing- 7, rin 23 vis preferably arrangedat' the upper Y en of the pipe 13,.so as to make the mouth of 9 'the ipe 13 correspond-in size to the opening int ebowl2.- I

It will readilybe seenthat-myconnection.

can be easily adjusted-accordingto the distanceof the 'flooriabove 'tlie'waste-pipe, by

simply allowing theend ofthe pipe 13 to en? ter a greater or less distance into-the cup "8 and then finingtheicup withlead or other seal-forming material. Whenthe seal has been placed, in position, the male and female members of the fcoupling' are'securelylockedj together, so that they W1ll not pull apart and also-sothatthe-pipe 13 or .themale member c will be held against turning while the circu 'la'r plate -15 is beingfiscrewed thereon. My

connection alsosimplifies the installation "of the lumbingsystem,.asthe same care will I not ave to-be exercised to secure perfect alinement of the wasteepipe with the floor,

roof

tion the pipe 13 can enter the cup 8 at an 311-- gle, if necessary.

With my coupling it is possible to form the seal either on the inside or the outside of the pipe-13, and this is quite an advantage, as in some cases, owing to the arrangement of the timbers of the floor, it is impossible-to form the seal on the outside of the pipe.

- What I claim is 1; The combination with a waste-pipe and a closet-bowlof a connection comprising an annular cup formed integral with the rim of the Waste-pipe, a pi e-section having one end arranged to exten into said cup and provided at its other end with means for. sup

porting the closet-bowl, a seal arranged -in said cup around the end of the'pipe-sectio'n and a ring arranged within said pipe-section and adapted torest on the inne'r wall of said cup, said ring havingabeveled inner face to serve as a deflector for material. passing through the pipe-section, substantially as described and for the purpose set forth.

2." The combination with a waste-pipe and 7 a closet-bowl of a connection comprising'an annular cup'formed integral with the rim of the waste'-pipe,.a pipe-section arranged to extend .into said cup, means for locking the pipe-section in the cup so as to prevent the withdrawal of the ipe-section from the cup or the turning oft e pipe-section in the cup and a deflector arrange within the pipe-section so as to rest on the rim of said cup for the purpose set forth.

3. The combination with a waste-pipe and a' closet-bowl of an annular cup formed inte' gral with the rim of the Waste-pipe, a straight pipe-section provided at one end with means for securing it to the closet-bowl and having its lower end extending into the said cup soas to divide the cup into two chambers, one of saidchambers being accessible from the exterioriof said pipe-section and the other,cham her being accessible from the interior of said pipe-section, and a seal arranged in said cup I around the end of said pipe-section, substam gialllyl as described and forthe purpose set ort 4. The combination with a waste-pipe'and a closet-bowl of a connection comprising anannular cup formed integral with the rim of the waste-pipe, a pipe-section provided at one end with means for securing it to the I closet-bowl and having its other end eiitehding down into said cup, projections arranged on the interior surface 0 lower end of said pipe-section, and a seal arrangedin said cup and forming a locking medium be'tween said projections so asv to prevent the said pipe-section turning in the said In testimony whereofl sign the foregoing.
